- MKMr K. S.Verified BuyerI do not recommend this productHow often do you dive? More than once a monthRated 2 out of 5 stars23 hours agoDisappointing.
Touted as suitable for diving masks, but despite precisely following the instructions, I found they came loose when water got in the mask (all masks get water in them at times, and they all need to be defogged initially). Luckily, they didn't come off the glass, they just moved around - which affected the vision.
They confirmed the prescription I needed so I'll buy replacement bi focal lenses for my mask.

You are quite right, this can happen occasionally when water enters the mask.
Prismaflex stick-on bifocal lenses are most suitable as a cost-effective solution for occasional dives.As you have found, for regular dives, a permanent bifocal is a better solution.

Easy to fit. You can experiment with the position.
Just had my 1st dive with them. Getting used to having 'bi focals'.
